DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 365,038, dated June 21, 1887.

Application filed March 9, 1887. Serial No. 230,187.

To aZZ whom it may concern.-

Be it known that I, FREDERICK XV. AN- DRES, a citizen of the United States, residing atYoungstown,in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Door-Checks; and I do hereby declare the following to be afull, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to that class of doorchecks which interpose an obstacle upon the inner side to the opening of the door from without, by means of a transverse barricade; and its object is a door barricade which is both ornamental in appearance, presents the greatest resistance to pressure or strain upon the door, and is readily adjustable from a hermetic lock to one equally rigid, but permitting the door to be opened for a greater or less space,as may be desired in each instance, so that at night, or when desirable, it re-enforces orsupersedes the ordinary keylock, which is liable to'be picked or broken open, and at other times allows the occupant of the room to control the entrance of persons from without after having been seen through the opening, thus constituting what I term a door safety-guard, of great value in protecting the inmates of dwellings and rooms against burglars and the uninvited ingress of tramps and other unwelcome persons.

In the drawings, Figure 1 is a face view of the eye-plate a, and Fig. 4 is an edge view of the same. Fig. 2 is a side vertical View of the key I). Fig. 3 is a face view of the lockplate 0, and Fig. 5 is an edge view of the same. Fig. 6 is a side view of a section of a door and casings with my safety-guard in place thereon as adjusted when a slight opening of the door is permitted.

Similar letters indicate similar parts in each view.

As will be understood by an inspection of the drawings, my door safety-guard consists of the chain d, extending from a permanent connection at one end with the eye-plate a on the casing,near the latch edge of the door,and preferably near the vertical center, to the (No model.)

locleplate c at the other end on a panel of the door, preferably at or near its center,where it has an adjustable connection, accomplishing the function stated.

My invention consists in the application of the chain in the manner and for the purpose stated, and in the mechanism of the parts a, I), and c. The eye-plate a is a flat, preferably rectangular, plate,having an eye extending at right angles with and from its surface to receive permanently an end link of thechain, and openings for screws, asa means of attachment to the casing. The locleplate 0 is also a flat,preferably rectangular, plate,with similar openings for screws, having centrally a vertical groove in and across its inner surface, formed by a semicircular curvature of the plate, the groove, when the plate is in place on the door, forminga vertical chamber. About midway between the upper and lower edges there is a rectangular and horizontal aperture through the plate to admit a link of the chain, so that the key Z), which is simply a short rod bent to a right angle at the upper end to form a head, locks the chain to the plate by passing through the inserted link as it rests in the groove or chamber. I make a and 0 preferably of cast-steel or malleable iron, the eye in a being cast solid therewith, providing at least four apertures for screws, as it is important that the plates befirmly fastened. These may bejapanned, or bronzed, ornickle-plated, for greater beauty of appearance, or may be made ofbrass, as preferred. On costly wood-work I place upon the side of the door near the edge where the chain impinges with stress a plate of metal tastefully ornamented, to prevent theabrading of the wood, and, if preferred, in lieu of the chain any flexible rope or strap of material that is not readily severed by an edge may be used.

It will be at once comprehended that by choice of the link of the chain to be used in the locking-plate the barricades, in the forms above described, may be created by my door safetyguard, and its usefulness will be at once appreciated.

I am well aware that barricades rigidly placed across a door from casing to casing, hermetically closingit, are old, and thatchains have been used for a similar purpose; but I am not awztre that the device above described the 1ink,which reaches the groove through an was ever known until my invent-ion thereof. opening in the plate, and the chain d, sub- What I c1aimis stantially as described, and ,for the purpose In door-fastenings, the adjustable door-barexpressed.
